BURNER FOR GAS-LAMPS.

SPECIFICATION forming part of Letters Patent No. 643,006, dated February6, 1900.

Application filed May 11, 1899. Serial No. 716,458. (No model.)

T0 at whom it may concern:

Be it known that I, RUDOLF J OH. WILH. REINHARD, manufacturer of metalgoods, a subject of the Emperor of Germany, residing at Hiihnerposten23, Hamburg, in the Empire of Germany, have invented certain new anduseful Improvements in and Relating to the Burners of Gas-Lamps, ofwhich the following is a full, clear, and exact description.

This invention relates to a device applicable to street gas-lampshavingdouble burners the jets of which are ignited by means of separateigniting-jets.

The object of this device is to enable the saidigniting-jets to beextinguished while the main jets are burning.-

This invention is illustrated in the annexed drawings.

Figure 1 shows in central sectional elevation a double-burnerstreet-lamp provided with this device. Fig. 2 is a side elevation ofFig. 1 in section on the line nu, Fig. 1. Fig. 3 is a front elevation ofthe body containing the regulating slide-valve in front end view, thelid being removed. Fig. 4 is a rear elevation of the same, likewise withthe lid removed. Figs. 5 to 8 show the various positions of the rotaryvalve. Figs. 9, 10, and 11 are crossed sections through theburnercarrier on the lines 00,11 y, and a cot Fig. 1.

According to this invention the essential part of the apparatus asillustrated consists in the slide-valve body A, which contains therotary slide-valve B. The body A is divided bya Vertical wall a, on thefront side of which, Fig. 3, there are arranged chambers I II III IV,which communicate at the top by means of holes 11 with the pipes o 0that convey the gas to the main jets, and by means of holes 2' i withthe pipes 0 0 that convey the gas to the igniting-jets. Each oft-hechambers is connected by means of a hole (chamber Z is connected by twoholes) with the space m behind the walla, into which the gas enters inthe direction of the arrow, Fig. 2, and in which the slide 13 issituated and bears firmly against the wall a. The pin 1) of the slide isled forward through the lid a of the chambers I to IV, and there it isprovided with a handle b Upon the back of the slide B there acts aspring b that is held. by means of a cover m, which closes in the spaceon and in which there is ter has been ignited by its own mainjet.

also situated a cleaning-screw m is formed with a gap .9, and accordingas this gap is moved in front of the holes which are formed in the walla and Which lead the gas to the chambers I to IV the gas passes into thepipes 0 0 o 0 and to the jets.

In the position shown in Fig. 4 the gas passes out of the chambers I toIV to the right and to the left hand through 4." o and 2' 0 to the twoigniting-jets. tinguished. In the position shown in Fig. 5 gas stillpasses to the right hand through i 0" to the igniting-jet and now alsoto the main jet on the left through i 0 The igniting-jet on the left isextinguished. If the slide is further rotated out of the position Fig.5, thenjin the position Fig. 6, the passage t o to the main jet on theright is opened; but the passage 6* 0 from chamber IV to theigniting-jet on the right is also still open, so that the main jet canbe ignited thereby, and then only after the slide has been rotated intothe position Fig. 7 the igniting-jet on the right is extinguished, andnow both main jets are burning. In the position Fig. 8 the main jet onthe right, which is fed throu h the assa e 2' 0 is burnin while 23 p b 3o the passage 1' o to the .main jet on the left has been shut after thepassage t" o to the igniting-flame has been opened and the lgt- Y reasonof the arrangementof the rotary slide it is rendered possible to arrangethe several passages (the holes which open from the gasspace m throughthe wall a into the chambers I to IV) at relatively great distances fromone another, so that in adjusting the slide-handle by hand largedifferences can occur at times without such differences interfering withthe desired supply of gas to the jets. The passages will even then bealways connected up together in the desired way, even though there be acertain amount of play in the setting or adjustment of the handle.

What I claim, and desire to secure by Letters Patent, is

The combination of the main jets, the igniter-jets, the separatepassages leading to the main and igniting jets each communicating withone of a series of annular gas-chambers separated from the maingas-supply by a partition but each communicating with the The main jetsare ex- The slide In witness whereof I subscribe my signature inpresence of two witnesses.
